Have my views changed? Absolutely. I do feel it's better if you at least think you love someone before having sex with them. But I've come to believe that the sex rules in the Bible were put there primarily to protect the family unit (avoidance of children born outside of a family unit) and the growth of the nation of Israel (masturbation law...if that's really even in the Bible. Something about wasting seed....) Now with (finally) reliable birth control methods, the whole no premarital sex thing is way overdone. Actually in the Bible it's not even as strict as in fundamentalist Christian cultures. I think a lot of that stems from the Victorian era...tho I haven't researched the subject in depth.
Honestly tho even when I was a witness I was never particularly uptight on the subject, and viewed sexuality as normal, not dirty, and perfectly natural once you are past puberty. I Think I've always looked at things from a biological lens. Still tried to follow the cultural rules to avoid guilt etc.
Regarding adultery, I do have empathy for the subjects. Life is complicated and often messy. I can't imagine being capable of having sex with someone else while married, but I can empathize with human weakness and maybe the loneliness it takes to get to that point.
Regarding gay sex...I used to think male gay sex was gross, female not so much (we are speaking honestly here...I'm not trying to be politically correct.) Now I think if that's what people desire then that's what's natural for them. Why should I think about other people's sex lives and what they do in private. As someone I knew once said 'i wouldnt come poop in your kitchen, you don't come poop in mine'....although thats more vulgar than I usually like to speak, I think about that saying often. Why don't we just leave each other's personal lives the heck alone.
